浅谈聚能管定向断裂爆破技术在岩巷中的应用

聚能管定向断裂爆破技术是利用聚能管改变巷道周边眼装药结构,爆破时,利用聚能作用控制裂隙的方向和数量,以获得较好爆破效果的技术。经过近一年的推广使用,已经取得了显著的效果。实践证明,这种爆破技术减少了对围岩的破坏,提高了成形质量,降低了材料消耗,有利于提高掘进速度和降低工程成本。

Discussion on Promotion and Application of Directional Fracture Blasting Technology with Shaped Tube in Rock Lane

Directional fracture blasting technology with shaped tube,which changes the eye charging structure of surrounding roadway with shaped tube to control the direction and quantity of fissure while blasting,has proved effective after nearly one year's promotion and application.Practice has proved that this kind of blasting technology reduces the destruction of the surrounding rock,improves forming quality and driving speed,and lowers material consumption and engineering cost.
